This is the authors' summary from a 34-page report. For a copy of the complete report, use the download link in the sidebar.

Fish populations in H-4 Reservoir were surveyed in 2019 using electrofishing, trap netting, and hoop netting and in 2020 using gill netting. Historical data are presented with the 2019-2020 data for comparison. This report summarizes the results of the surveys and contains a management plan for the reservoir based on those findings.

Reservoir Description

H-4 is a 696-acre reservoir on the Guadalupe River in Gonzales County and is controlled by the Guadalupe-Blanco River Authority (GBRA). The reservoir was impounded in 1931 to provide water for hydroelectric generation and recreation. The substrate was primarily silt, sand, clay with some gravel and rock. Angler and public boat access are limited to one pay-to-use boat ramp and there are no handicap-specific facilities. Primary habitat is composed of boat docks and piers, timber, native floating-leaved and submersed vegetation, hydrilla, and water hyacinth.  

Management History

Important sport fish species include Channel Catfish, Largemouth Bass, and crappie. Anglers have reported catching White Bass, Palmetto Bass, and Striped Bass from this reservoir, but these species have not been collected in any survey. Blue Catfish were stocked historically, but relative abundance remains low. The 2016 management plan focused on utilizing additional fishing gear methods to better assess declines in sport fish populations and continuing to assist GBRA with nuisance vegetation control.
